WILLIAM F. TRAUDT, OF BUFFALO, YORK, ASSIGNOR TO IABER PUMP COM- PANY,OF BUFFALO, NEW YORK, A CQR-PORATION F NEXV YORK.

PORTABLE POWER-DRIVEN PUMP.

Application filed March 7, 1928.

This invention relates to portable pumps and comprises a pumping unitwhich can be moved about and hung over the side of a receptacle to pumpout liquid therefrom, or set up in a flooded cellar or shallow streamfor the same purpose. To this end it consists of a rotary pump andusually an electric motor both mounted .on a light weight bed frame, andadapted to operate in a perpendicular, or approximately perpendicular,position said bed frame being provided with an adjustable suspensionhook and an easel-like supporting strut, or other supporting foot.

The best form of apparatus at present known to me embodying my inventionis illustrated in the accompanying three sheets of drawings in whichFig. 1 is a front elevation of one form of the apparatus, with partsshown in section.

Fig. 2 is a side elevation showing one form of support for the apparatusin section and broken away and another in broken lines.

Fig. 8 is a detail View showing the pump with a supporting foot for thebed frame, used as shown in Fig. 4c.

Fig. 4 is a side View on smaller scaleof the apparatus, set up for oneof the uses for which it is designed.

Fig. 5 is a plan view of another form of foot for the pump supportingstructure.

Fig. 6 is a side elevation showing the same applied to a pump structure,and

Fig. 7 is a detail rear elevation of this form of foot, i. e. a viewlooking from the right hand side of Fig. 5.

Throughout the drawings like reference characters indicate like parts. i

1 is a rotary pump preferably having a central inlet 5 and acircumferential discharge connected to the pipe 6. 2 is a bed frame oflight weight, preferably a piece .of channel iron, to which the pump 1and electric motor 3 are fastened, with the driving shaft 1 connectingthe two, so that the motor may rotate the pump. 7 is an eyebolt screwedinto bed frame 2 to firmly hold the upper end of discharge pipe 6, sothat when. it is attached to a hose or system of piping by a couplingsuch as the elbow 6", employing a screw connection, the pipe may not betwisted away from the bed frame by any unnecessary force which theoperator may apply in making the screw connection.

Serial No. 259,764.

8 is a hook projecting from the backof the bed frame 2 and fastened tothe same by bolts 9, 9, the hook being adjustable lengthwise along saidbed frame 2-by shiftlng bolts 9, 9, into different holes of the series'9, indicated in dotted lines in Fig. 2. By means of this hook engagingthe edge of a liquid receptacle such as is indicated at 18, the entireapparatus may be suspended with the pump immersed in the liquid in saidreceptacle, the hook being adjusted in position according to the depthof the receptacle.

10 is a switch for the electric motor connections operated by thefloat11, and connecting rod 12, so that the pump may be automatically stoppedwhen the level of the liquid in the receptacle. reaches a predeterminedpoint.

An additional means of support for the apparatus usable in othersituations comprises the strut 13, vertically adjustable in the sleeve14, where it is held by set screw 15, said sleeve being pivoted to theupper end of the bed frame 2 at 16, so as to form, with said bed frame,an easel-like structure which may be set up in a shallow stream, asshown in. Fig. 4, for the purpose of pumping water therefrom, or loweredinto a flooded cellar for the purpose of pumping water out of it. Tofacilitate this action, the lower end of the bed frame 2 is providedwith a laterally extending foot piece 17, which may be bolted thereto,as best shown in Fig. 3.

Still another form of supporting foot is shown in Figs. 5, 6 and 7,where 19 is a circular, metal base plate having the upright flanges 20and 21 to which the pump bed frame 2 may be bolted, as shown in Fig. 6,or otherwise fastened. 22 is a backing rib for flange 21, and 2 is aboss corresponding to the cross section of channel iron bed frame 2, onwhich the end of said channel iron may rest.

In operating the apparatus, it is hung over the edge of the liquidreceptacle by means of hook 8, as shown in Fig. 2, or set up like aneasel with the pump submerged in the body of liquid on which it is tooperate, as shown in Fig. 4:, or set on the foot plate, as shown in Fig.6, the parts being ad justed to place the bed frame 2 in a vertical orapproximately vertical position so that the motor 3 will not besubmerged. When the apparatus is used to pump out a receptacle like acistern having a wall over, or on the edge of which, hook 8 can berested, as indicated in Fig. 2, the lower supporting foot, such as 17-,is also useful in pre venting the lower end of the apparatus fromswinging away from a vertical line and to hold the entire apparatus inproper position. After the contents of the cistern have been pumped outdown to level nearly that of the suction opening of the pump, theapparatus can then be unhoolred and stood up on the bottom of thecistern through the action of the foot 19, the hook 8 then restingagainst the side wall of the cistern and still contributing to thesupport of the apparatus.

While I have illustrated an electric motor, other small motors might besubstituted as the driving member of the apparatus.

The advantages of the invention comprise its cheapness, lightness, easeof portability and facility for locating in operative position in anyone of many diiferent situations, where water has to be removed foremergency purposes, or obtained during a short period of use.

Having described my invention, 1 claim:

1. The combination, with a rotary pump, a motor and a driving connectionbetween the two, of a light-weight bed frame adapted to support saidmotor above said pump,

and a hook mounted on said bed frame for temporarily engaging anyconvenient support for the entire structure, whereby it may be suspendedfrom the side wall of a liquid container with the pump submerged in thel quid, said hook being adjustable lengthwise of said bed frame.

2. The combination, with a rotary pump, a motor and a driving connectionbetween the two, of a light-weight bed frame adapted to support saidmotor above said pump, a transversely extending foot piece on the lowerend of said bed frame, and an adjustable strut pivoted to the other endof said bed frame, whereby said structure may be set up in a liquidreceptacle with the pump submerged in the liquid.

The combination, with a rotary pump, a

motor and a driving shaft connecting the r two, of a lightweight, narrowbed frame adapted to support said motor above said pump, supportingmeans mounted on the up per portion of said bed frame adapted forengaging any convenient support for the entire structure, and asupporting foot piece fastened to the lower end of said bed frame andadapted to cooperate therewith and with said upper supporting means tomaintain the above described structure in substantially verticalposition.
